I wanna start doing things with this car and an intake is always a nice easy cheap first step but… is their really any point? Its just a silicone tube and a drop in filter so your not gaining much/any power from that, but thats also never really been the point with an intake, its the audio gains that intakes have always helped with and i doubt there is going to be any increase in intake noise with this. Honda v6’ have always had great intake noise and i was hoping that we would have something coming out that would assist with that. Thoughts?
According to a blog post from PRL, the stock intake system is well designed in their opinion minus the stock intake tube which doesn’t provide smooth airflow to the turbocharger. The air filter drop-in should be good for a few HP since it allows more airflow, but without a before and after comparison, we can sit here and speculate all we want. Considering the TLX-S platform is still fairly new, it’s great to see they’re taking the lead.
Just speculation but it would have been cheaper I think for Acura to provide a hose over what they do use.
Might be worth while to find out why the are using the current pipe. That said most CAI's in real life don't do much but make a nice noise.
More airflow = less filtration. You want more air flow just buy a performance filter for the stock case. Thing is you need more airflow only if the current airflow is insufficient to feed the turbo at WOT.

OEM does a pretty good job nowadays maximizing their intake systems while retaining the filtration levels needed to maintain engine longevity. As Bear mentioned, aftermarket filters filters less particles which find their way into the oil. Perhaps with this type of filter, the turbo spooling and BOV will be more audible, which sounds like something you already know.
When I had my FK8, Hondata published an interesting article testing different brands of intakes vs OEM and found OEM made same, or more power, than the aftermarket brands. Considering the FK8 engineers had a role in developing this engine, results will probably be the same.
I personally prefer new OEM intake filters versus cleaning and reusing the same one.

Agree. Another thing to think about is the actual size of the tube which is specifically calibrated at the factory. Example:
This is paper non-oiled filter on a 4" tube of a specific length, filter base to throttle body face. It also incudes an air sensor mount. Engine is a mild tune with 488WHP on DynoJet.
5.0L 32 Valve DOHC V8. What you don't see in the 3.5" sleave inside the first short section of the tube at the sensor to correct the air flow as a 4" tube is too big. Bigger is not always better. In general manufactures do a lot of work on their intake systems.
Food for thought. In one of my other pictures on a brand that will remain nameless there are two paper aftermarket filters one for each turbo highly visible. That car was baseline dynoed stock on a DynoJet at 319/321WHP on the factory intake. The factory system was good to just over 401whp before the factory stock intake was restriction to air flow.
Funny thing the sensor is at the 9 o'clock position. If the sensor was placed in a different position say 3 o'clock the engine would stumble on acceleration. There is a lot of science in these things. This specific configuration was designed by FORD racing for their crate engines going into the Cobras.
